On Sunday, CNN reported that the CDC held a video conference with approximately 800 staff members to discuss the traumatic event and allow them to ask questions. Staff said they felt like "sitting ducks" as bullets whizzed just over their cubicle walls and they dove for the floor.

On Friday after the shooting, the Trump administration was relatively quiet, according to the Atlanta Journal-Constitution: The White House had not made a comment, and Kennedy had only reposted a social media statement from CDC Director Susan Monarez about the shooting.

Adams, who served as surgeon general during the first Trump administration, said Kennedy's assertions about the efficacy of mRNA vaccines are "simply not true."
